I know you’re not my biggest fan. But I use this humidifier with great success. Cheap and has an RH setting. It does need to be level to work properly - I discovered that after setting it on an uneven floor.
i use a humdifier i picjed up at walmart for $22 holds a gallon in the resivoir has 3 settings and keeps my 2x2 tent at about %55 i only use it as a drying tent seems to do a great job as i put a 4 inch fan up top for exhaust and leave the vent open on the bottom
Okay, setting this one I just got at 55% got me 35% with the door shut on a 11’x11’x8’ room after about 12 hours with humidity inside the rest of the house at 22%. Will probably have to increase the intensity setting from medium to high and set it at around 65% or 70%, then add water every two days.
